sArEr-Y RAZOR. v

Application led November 2, 1920i Serial No. 421,262.

To all fio/0m t may concern Be it known that I, THOMAS W. STEWART, a citizen of the United States, and a resident of South Sioux City, in the county of Dakota and State of ebraska, have invented.

certain newy and useful Improvements in Safety Razors, of which the following is a specification.

My present inventionrelates, no doubt,tol

safet razors et itis more articularl intended for scraping or shaving carcasses,y

the invention having, for its principal object, the production of an improved and simplified device for removinghair from those portions of the carcasses which the means usually employed for the purpose fail to reach.

A further object of the invention is the production of a carcass-scraping device particularly adapted for scraping hair froml convex and concave surfaces of carcasses.

,Furthermore the invention contemplates a carcass-scraping device comparatively inexpensive and simple in construction and Fig. 4f is a plan of the device' as constructed for shaving convex surfaces, and

Fig. 5 `is a rear elevation thereof.

lVhile I have illustrated and hereinafter described a preferred embodiment of the invention, I would not be understood as being limited to such specific construction, for various alterations and modifications may be made in the details of construction andarrangements of parts herein disclosed without departing from the spirit and scope of they invention as defined in the appended claims. f

Referring now more particularly to Figures 1 to 3, 5 represents the guard or bladesupporting means, which consists of an elongated plate, bent'longitudinally, forming in plan view a crescent shape, as presented in Fig. 1, the lower edge of the said plate being notched, as at 6, exposing` the sharp edge of a blade, 7, held firmly in conformity with and against the outer or front face of the plate, 5, as by providing overturned ends, 8, on the guard-plate, 5, which engage the ends of the blade, 7, theintermediate portion of the guard-plate is provided with means serving both as a handle for the device and means for firmly clamping the blade and' guard-plate together, the said means preferably consistingy of a short cylinder, 9, positioned above thedeviceand having a depending part, 10, suitably secured, as at 11,

\ to the intermediate portion of they guard.

Within the cylinder, 9, freely rotates a cylindrical nut, 12, provided at its forward p end with ra boss, 13, which prevents rear-` ward movement of the nut, its rear end being reduced, as at 14, to enter and be secured to a suitable handle, 15, which prevents forward movement of the nut, yet permits free rotation of the latter within they cylinder, 9.

Into the nut, 12, is rthreaded a bolt, 16, pro-r jecting rearwardly from a plate, 17, which embraces the front of the intermediate portion of theblade, 7. By virtue o'fthis construction, it is clear lthat rotation of the handle in one direction clamps the blade firmly to the guard, whilev rotation in the opposite direction will loosen,and permit separation of the parts.k

The frame above set forth is obviously in tended for application to concave surfaces or recesses which would not be reached readily by a straight blade while the form shown in Figs. a and '5 is for use on convex surfaces, theguard plate, 5, being concavo-convex, but bent oppositely to the previously `and the blade, 7, be-y described construction, ing positioned on the concave side thereof, and its intermediate portion held firmly againstthe plate by means of the handle, 15, and associatedparts,

Having thusdescribed my invention, what I claim as new and desire to secure by Letters- Patent of the United States is:

A device of the class describedcomprising an elongated rigidguard plate curved longitudinally in a crescent shape, the end portions of the plate being overturned, a sharpedged blade restingagainst the face o' the plate and engaged by said overturned end portions, and a handle and securing means, including a clamp member engaging the intermediate portion of the exposed face of the blade, a bearing member carried by the plate, a handle, a nut fixed on the handle,

and rotatable Within the bearing member, and a bolt projecting from the clamping member, and threaded into the nut.

In testimony whereof, I have hereunto set my hand this 19th day of October, 1920.

THOMAS STEVART.
